Madeira

Madeira's volcanic Atlantic island produces some of the world's most singular and longest-lived wines. Fortified Madeira ages through deliberate heating (estufagem) or natural attic warming (canteiro), gaining its trademark oxidative complexity, baked-fruit notes and razor-sharp acidity — bottles a century old remain vibrant. The four classic noble grapes — Sercial (driest), Verdelho, Bual and Malmsey (sweetest) — define a sweetness ladder, with Tinta Negra used for entry-level and increasingly for serious bottlings. Beyond the fortified style, table wines and dry whites from the island are slowly emerging.
